Perfect
I had a hard time finding an evaporative cooler pillow/vent plug. I checked many stores and it was going to take a long time for them to ship it. I got this in two days I do wish I ordered a bigger size but I didn’t realize at the time… because I didn’t measure so that’s on me. Does a great job at stopping any air flow. It’s really good quality I would order it again and it shipped fast. In the future I’d recommend purchasing a bigger size, it’s better to squish it up there than to have it fall out.

Smartest thing I’ve ever done…
Talk about a draft… last winter I moved into my sister’s trailer and we just had the cooler covered on the outside. There was a TON of cold air coming in and covering it and taping it off didn’t seem to help much. So this year I found one of these puppies and boy am I glad I did! No drafts, no leaks, this thing is wonderful! Highly recommended for anyone with a swamp cooler!!!

Fits perfectly, trapping heat inside!
This was a brilliant option for me, as I have struggled with the magnetic vent covers that never work. This fit beautifully and I can visualize the heat staying INSIDE my house rather than escaping through my swamp cooler vent.

Good solution
This item fits perfectly and does a much better job than my homemade block. It’s only been in place a few weeks, but the absence of a cold draft is welcome.

Stiff
The cover on this has held up to a couple of rough sessions and held in place through the winter just fine. That said it is almost too stiff and I felt it didn’t create the best seal in the vent.

Keeping climate outside!
These work not only as swamp cooler plugs but also as window insulation used with vertical blinds. They keep the heat out I summer, the warmth in in winter and stop the cats from walking in the internal windowsills.

Great fit
It’s perfectly in my cooler duct to block the warm air from escaping out the roof, my only gripe is it took forever to get it shipped
